C# C VSTS工作项相关计数字段显示为零，即使我看到VSTS web应用程序中的相关链接

我正试图从我们的VSTS托管环境中提取一些信息，我需要将其作为报告呈现。我观察到，API库报告没有与该工作项相关的项目，尽管我看到了VSTS web应用程序中的相关链接

这是我的密码-

void Main()
{
    string url = "https://[redacted].visualstudio.com";
    string token = "[redacted]";
    string project = "[redacted]";
    string version = "[redacted]";

    VssConnection conn = GetConnection(url, token);
    WorkItemTrackingHttpClient witClient = conn.GetClient<WorkItemTrackingHttpClient>();

    Wiql q = new Wiql();
    q.Query = $"SELECT * FROM WorkItems WHERE [System.TeamProject] = '{project}' AND [System.Tags] CONTAINS '{version}' AND [System.WorkItemType] IN ('Product Backlog Item', 'Defect') ORDER BY [System.CreatedDate] desc";

    var qi = witClient.QueryByWiqlAsync(q).Result;
    var ids = qi.WorkItems.Select(x => x.Id);
    var workitems = witClient.GetWorkItemsAsync(ids).Result.Select(r =>
    {
        return new
        {
            ItemId = r.Id,
            ItemAssignedTo = r.Fields["System.AssignedTo"],
            ItemCreatedBy = r.Fields["System.CreatedBy"],
            ItemTitle = r.Fields["System.Title"],
            ItemType = r.Fields["System.WorkItemType"],
            State = r.Fields["System.State"],
            ItemHasDescription = r.Fields.ContainsKey("System.Description") ? "Yes" : "No",
            ItemHasAcceptanceCriteria = r.Fields.ContainsKey("Microsoft.VSTS.Common.AcceptanceCriteria") ? "Yes" : "No",
            RelatedItems = r.Fields.ContainsKey("System.RelatedLinkCount") ? r.Fields["System.RelatedLinkCount"] : null //This line reports no related links,
            Links = r.Links != null ? r.Links.Links : null //So does this line report null
        };
    });
    workitems.Dump();
    conn.Disconnect();
}

private static VssConnection GetConnection(string accountUri, string personalAccessToken)
{
    var cred = new VssBasicCredential(string.Empty, personalAccessToken);
    VssHttpMessageHandler vssHandler = new VssHttpMessageHandler(cred, VssClientHttpRequestSettings.Default.Clone());
    return new VssConnection(
                        new Uri(accountUri),
                        vssHandler,
                        new DelegatingHandler[] { new SuppressHandler() });
}

public class SuppressHandler : DelegatingHandler
{

}

有没有办法删除这些控制台日志记录？

无法根据您的代码找出问题所在

但是，您可以使用下面的代码示例从VSTS检索工作项信息，它在我这边起作用：

要避免获取这些控制台日志，可以禁用程序输出：

在“输出”窗口中单击鼠标右键->取消选择“程序输出”选项，然后重试

            string PAT = "TokenHere";
            string project = "ProjectName";

            VssBasicCredential credentials = new VssBasicCredential("", PAT);

            //create a wiql object and build our query
            Wiql wiql = new Wiql()
            {
                Query = "Select * " +
                        "From WorkItems " +
                        "Where [Work Item Type] IN ('Product Backlog Item', 'Task') " +
                        "And [System.TeamProject] = '" + project + "' " +

            };

            //create instance of work item tracking http client
            using (WorkItemTrackingHttpClient workItemTrackingHttpClient = new WorkItemTrackingHttpClient(uri, credentials))
            {
                //execute the query to get the list of work items in the results
                WorkItemQueryResult workItemQueryResult = workItemTrackingHttpClient.QueryByWiqlAsync(wiql).Result;

                {
                    //need to get the list of our work item ids and put them into an array
                    List<int> list = new List<int>();
                    foreach (var item in workItemQueryResult.WorkItems)
                    {
                        list.Add(item.Id);
                    }

                    fields[2] = "System.RelatedLinkCount";

                    //get work items for the ids found in query
                    var workItems = workItemTrackingHttpClient.GetWorkItemsAsync(arr, fields, workItemQueryResult.AsOf).Result;

                    Console.WriteLine("Query Results: {0} items found", workItems.Count);

                    //loop though work items and write to console
                    foreach (var workItem in workItems)
                    {
                        Console.WriteLine("ID:{0} Title:{1}  RelatedLinkCount:{2}", workItem.Id, workItem.Fields["System.Title"], workItem.Fields["System.RelatedLinkCount"]);
                    }

                    Console.ReadLine();
                }
            }

我刚刚遇到了一个类似的问题，您需要做的是使用GetWorkItemAsync方法的WorkItemExpand参数，如下所示：

var item = client.GetWorkItemAsync(c_projectName, id, null, null, WorkItemExpand.Relations).Result;

---

如果不使用Relations属性，则该属性为null，这会产生很大的误导。如果使用，它将存储有关相关工作的正确信息。

Ok我缺少IEnumerable fields参数。一旦我通过了，我就会看到相关链接计数。但是WorkItem.Links属性仍然为空。如何获取相关项目的实际Id？我在LINQPad中尝试了这一点，因此输出在那里并不真正适用。还有其他方法吗？@SohamDasgupta实际Id包含在关系->url中，它不是工作项字段。所以我认为您不能直接获取ID，您可以在循环中检索相关的工作项，然后获取它们的ID。在LINQPad上没有任何经验，不知道如何删除控制台日志记录…这是我之前尝试告诉您的，Relations属性显示为null，否则我现在已经提取了工作项：@SohamDasgupta是的，你可以在另一个线程中引用我的答案，用RESTAPI检索链接的工作项ID：谢谢，但是你知道为什么API不能按预期工作吗？我的意思是，使用API的全部目的是确保我不必乱搞RESTURL。

var item = client.GetWorkItemAsync(c_projectName, id, null, null, WorkItemExpand.Relations).Result;
